angular velocity
A rubber ball with a radius of 3.2 cm rolls along the horizontal surface of a table with a constant linear speed 'v'. When the ball rolls off the edge of the table, it falls 0.66m to the floor below. If the ball completes 0.37 revolutions during its fall, what was its linear speed?

$t = \sqrt{\frac{2h}{g}}$

$v = \frac{r \Delta \theta}{t}
